Adata SD600 external SSD takes 3D NAND on the go
 

External drive buyers can have unique priorities. Some want 8TB of storage and are willing to put up with the relative fragility and low performance of spinning platter disks. Other want speed and portability, and Adata's SD600 external SSD nicely fits that bill. The SD600 series includes 256GB and 512GB models built with 3D NAND flash. The SSDs operate over the USB 3.0 interface and boast DRAM and SLC buffer caches for increased performance.
